    Mar 17, 2017· In its early days flotation promised, not only the ability to treat slime, but also a great simplicity of flowsheets attributable to the fact that all that had to be done was to grind the ore to a fine pulp and then float it. Flotation was the powerful new tool to which all refractory ores would respond.

    OverviewPrinciple of operationHistoryIndustriesScience of flotationFlotation equipmentMechanics of flotationChemicals of flotation

    Before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains. This process is known as liberation. The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes a
